   What is a primary use case for block storage compared to file and object storage?

   • ASharing files across multiple EC2 instances with POSIX permissions
   • BServing static website content over the internet
   • CProviding low-latency storage for a database running on a single EC2 instance
   • DArchiving data for long-term retention

   A company runs a NoSQL database (e.g., Cassandra) on a cluster of EC2 instances. Each instance stores data on an EBS volume. The workload requires low-latency reads and writes with a baseline of 10,000 IOPS and the ability to burst to 20,000 IOPS for short periods. The company wants to minimize cost. Which EBS volume type should they use?

   • AThroughput Optimized HDD (st1)
   • BCold HDD (sc1)
   • CProvisioned IOPS SSD (io2)
   • DGeneral Purpose SSD (gp3)

   A company runs a high-performance computing (HPC) workload on a cluster of EC2 instances. The workload requires a shared file system with very high throughput (multiple GB/s) and low latency. The company has evaluated Amazon EFS and found that the default Bursting Throughput mode does not provide sufficient throughput. Which configuration should they use to meet the performance requirement?

   • AUse EFS with Elastic Throughput mode, which automatically scales throughput with workload demand.
   • BUse EFS with Bursting Throughput mode and increase the file system size to accumulate more burst credits.
   • CSwitch the EFS file system to Provisioned Throughput mode and set a higher throughput value.
   • DMount the EFS file system with the NFS over TCP protocol to improve throughput.

   A research organization runs a cluster of 12 EC2 instances that collaboratively process genomic data. The application requires a shared file system with POSIX permissions, sub-millisecond latency, and the ability to scale throughput as the number of instances grows. The data is accessed concurrently by all instances. Which storage solution should the organization use?

   • AAmazon S3 with S3 File Gateway mounted on each instance
   • BAmazon EBS with io2 Block Express volumes attached to each instance
   • CAmazon EFS with Elastic Throughput mode
   • DAWS Storage Gateway Volume Gateway with iSCSI volumes shared via a cluster file system

   How does object storage differ from file and block storage in terms of data organization?

   • AObject storage uses a hierarchical folder structure
   • BObject storage organizes data into volumes and partitions
   • CObject storage requires a file system to manage data
   • DObject storage stores data as objects with metadata and a unique identifier
